Two ends of the liquid absorbing wick 141 are respectivelyarranged in the two opening grooves 1531 and extend into the liquidflowing channels 1532 to be in communication with the liquid storagecavity 110 in a liquid guiding manner.

In some embodiments, the vaporization base 13 may be integrally formedby an elastic material such as silicone, and may include a sleeve part131 arranged on a lower part and a body portion 132 arranged on an upperpart. The sleeve part 131 is annular and sleeved in a sealing mannerbetween the upper shell 11 and the carrying portion 153, so as toachieve a sealing effect and avoid liquid leakage. The vaporization base13 may further include two pressing portions 133 formed by downwardextension of the two opening grooves 1531 corresponding to two sides ofa bottom part of the body portion 132 respectively. The two pressingportions 133 respectively press the two ends of the liquid absorbingwick 141 and may form a seal structure to avoid a case that the liquidvaporizable substrate in the liquid storage cavity 110 enters thevaporization cavity 150 and causes liquid leakage.

Moreover, few parts indicate a small cumulativetolerance, so that assembling and sealing are reliable.

Two liquid guide holes 1310 are formed between an inner wall surface ofthe sleeve part 131 and an outer wall surface of the pressing portion133, where the two liquid guide holes 1310 are provided corresponding toand in communication with the two liquid flowing channels 1532respectively, so as to communicate the liquid storage cavity 110 withthe two liquid flowing channels 1532. An air guide channel 1311 may befurther formed on an outer peripheral wall of the sleeve part 131, wherethe air guide channel 1311 may communicate the liquid storage cavity 110with the outside to supply air to the liquid storage cavity 110, so asto realize air-liquid equilibrium and smoother liquid flowing from theliquid storage cavity.

Specifically, in this embodiment, a plurality of horizontal annularprotrusions 1313 and a plurality of horizontal annular grooves 1312 areformed on the outer peripheral wall of the sleeve part 131. One annulargroove 1312 is formed between every two adjacent annular protrusions1313, and an air inlet opening 1314 is provided on a side of eachannular protrusion 1313 so as to communicate every two adjacent annulargrooves 1312 in an up-down direction thereof. The plurality of air inletopenings 1314 and the plurality of annular grooves 1312 are incommunication to form the air guide channel 1311. The air inlet openings1314 of the plurality of annular protrusions 1313 may be provided on thesame or different sides of the sleeve part 131. In this embodiment, theair inlet openings 1314 of every two adjacent annular protrusions 1313are respectively provided on two opposite sides of the sleeve part 131in the longitudinal direction. In addition, the annular protrusions 1313are interference-fitted in the upper shell 11, bringing a better sealingeffect. The annular grooves 1312 may also absorb and store a certainamount of leaked liquid by a capillary force, so as to further reduceliquid leakage. When air pressure in the liquid storage cavity 110decreases (for example, when the electronic vaporization device istransported by an airplane), volumes of air bubbles in the liquidstorage cavity 110 increase, and the liquid vaporizable substrateoverflowing through the air guide channel 1311 will be accommodated inthe annular grooves 1312, thereby reducing liquid leakage. When the airpressure in the liquid storage cavity 110 returns to normal, the liquidvaporizable substrate stored in the annular grooves 1312 may reflux tothe liquid storage cavity 110 through the air guide channel 1311,thereby improving reducing negative pressure liquid leakage. A width ofeach of the annular grooves 1312 may range from 0.1 mm to 0.5 mm, andpreferably range from 0.2 mm to 0.4 mm.

A bottom surface of the body portion 132 may abut against the topsurface of the carrying portion 153, and a through hole 130 is providedthrough the body portion 132 in the longitudinal direction. The throughhole 130 may include a first hole section 1301 and a second hole section1302 that are in communication sequentially from bottom to top, and apore size of the second hole section 1302 is larger than that of thefirst hole section 1301. A lower end of the air outlet tube 111 isclosely embedded in the second hole section 1302 and is in communicationwith the first hole section 1301, and a lower end surface of the airoutlet tube 111 may abut against a step surface 1304 formed between thefirst hole section 1301 and the second hole section 1302. An inner wallsurface of the second hole section 1302 may further protrude radiallyinward to form at least one annular seal portion 1305, where the annularseal portion 1305 is in interference fit with the air outlet tube 111 toimprove sealing performance. The first hole section 1301 is providedcorresponding to and in communication with the vaporization cavity 150,and the pore size of the first hole section 1301 is the same as an innerdiameter of the lower end of the air outlet tube 111, so that the vapormay flow out more smoothly. A chamfer 1303 may be arranged at a bottompart of the first hole section 1301, where the chamfer 1303 may reduce avortex flow, and the vapor in the vaporization cavity 150 flows outalong the chamfer 1303, so that the vapor may flow out more smoothly.

Therefore, the air inlet hole 210, the mounting cavity 2111, the ventgroove 2110, the air inlet channel 220, the air guide groove 1510, thevent hole 1501, the vaporization cavity 150, the first hole section1301, and the air outlet channel 1110 are in communication sequentiallyto form a complete vapor conveying channel.

As shown in FIG. 2 and FIG. 7 , in some embodiments, the vaporizer 1 mayfurther include a mouthpiece sleeve 12. The mouthpiece sleeve 12 may beintegrally formed by a silicone material, and may include an outersleeve 121 sleeved outside an upper end of the upper shell 11, a sealingplug 122 extending downward from a top part of the outer sleeve 121, andan edge dismounting groove 123 surrounding the sealing plug 122. Thesealing plug 122 is plugged in a sealing manner in an upper end of theair outlet channel 1110, and the edge dismounting groove 123 is annularand may be formed by an inner wall surface of the outer sleeve 121recessing inward. A shape and a size of the edge dismounting groove 123match a shape and a size of an exit of the air outlet channel 1110. Forexample, the size of the edge dismounting groove 123 may be the same asor slightly larger than the size of the exit of the air outlet channel1110. The mouthpiece sleeve 12 may not only block and close thevaporizer, but also separate the sealing plug 122 by tearing an edgedismounting groove structure. After the sealing plug 122 isdisassembled, the outer sleeve 121 may be used as a protective sleevewhen a plurality of people share and use the product (that is, otherpeople may use the electronic vaporization device through the outersleeve 121).
